Aim: The goal of this project is to:

Methodology:

The project would lay more emphasis on the explanatory techniques. It will be used in making data presentation to the viewers in a more succinct way. I therefore plan to use the R programing language to explore and analysis the dataset.

The dataset to be used is the World Health Nutrition and Population Statistics from year 2010 to 2016 . This can be obtained from http://databank.worldbank.org/data/reports.aspx?source=health-nutrition-and-population-statistics#advancedDownloadOptions .

Load this libraries and dataset and lets get to work!

INCIDENCE RATES

“Incidence rate or person-time rate is a measure of incidence that incorporates time directly into the denominator. A person-time rate is generally calculated from a long-term cohort follow-up study, wherein enrollees are followed over time and the occurrence of new cases of disease is documented.”" —CDC

\(Incidence\quad Rate\quad =\quad \frac { Number\quad of\quad newcases\quad of\quad disease\quad or\quad injury\quad during\quad specified\quad period }{ Time\quad each\quad person\quad was\quad observed,\quad totaled\quad for\quad all\quad persons }\)
